On 7 October, the first snow fell, turning the roads into mud and forcing the3rd Panzer Group's advance to a halt. The snowy conditions allowed the army to set up defensive positions along the Zhuravlyovo − Bolshoye Yakovtsevo − Ivashkovo line and form a corridor for retreating Soviet units. This began the Kalinin Defensive Operation phase of theMoscow Strategic Defensive operations.
